BACKGROUND OF THE INVENTION

Embodiments of the invention generally relate to mobile communicationsdevices and wireless networking. More specifically, they relate tosystems and methods for efficiently determining location information ofmobile communications devices.

GPS chipsets and other location determination technology have advancedrapidly over past few years. Technology related to mobile communicationsdevices, and the networks upon which they operate, have seenbreakthroughs as well. Relational databases and computers systemsrepresent another area that has also seen significant advancement. Thereare significant opportunities for integration of these differentsystems, devices and technologies to provide new functionality.

One of the larger hurdles to deployment is the power constraintsinherent in many mobile communications devices. This limits theprocessing that can take place on the devices, and thus limits theirfunctionality. Many services that leverage location information arepower intensive on the device, and thus have not been deployed in manytypes of devices. For example, mapping software, which creates mapsbased on GPS location information, is often loaded on to mobile devices.However, this type of functionality requires significant processing, andthus serves as a significant drain on many mobile communication devices.Thus, there exists a need in the art to leverage these advancedtechnologies, while efficiently using the limited power available on adevice.

In addition to providing location based information only to the user,the sharing of location based information may provide benefits. Givenprivacy concerns, users will not want to share their locationinformation all of the time and to everyone. These privacy concerns arean impediment that currently limits the sharing of such information.However, there are specific instances in which sharing locationinformation is of significant value. For instance, letting friends andother family members know a user's location can be important for safetyand coordination reasons. Also, sharing information with certainproviders of products and services in user defined circumstances mayprovide value as well. Thus, there exists a need in the art for systemsand methods of sharing location based and other user information, whilefiltering access to that information.

Exemplary cellularsystems include, but are not limited to, time division multiple access(“TDMA”) systems, code division multiple access (“CDMA”) systems, andGlobal System for Mobile communications (“GSM”) systems. Other exemplarycellular systems include systems known in the art as “3G” systems,Enhanced Data Rates for GSM Evolution (“EDGE”) systems.

In some embodiments, the Mobile Communications Base Station 120 may becommunicatively coupled or otherwise in communication with standardcellular network components known in the art. The Mobile CommunicationsBase Station 120 may be in communication with a mobile switching center(“MSC”). To provide connectivity between cellular subscribers, the MSCmay also be in communication with a telephone network such as the publicswitched telephone network (“PSTN”), and may query or otherwise utilizea Signal Control Point, additional components that are well known tothose skilled in the art.

The Mobile Communications Base Station 120 may also be comprised of awireless access point which sends and receives radio signals to and fromthe Mobile Communications Device 125. Such a wireless access pointincludes any device that provides a wireless interface and providesconnectivity to the Server Computer System 105. By way of example, suchaccess points may be “WiFi” hot spots that comply with the wirelessstandards developed in association with IEEE 802.11, including, but notlimited to IEEE 802.11(a), IEEE 802.11(b), IEEE 802.11(g), and IEEE802.11 (n), which is currently under development. Those skilled in theart will recognize the myriad of potential configurations surroundingthe Mobile Communications Base Station 120. Under these embodiments, theServer Computer System 105 communicates with the Mobile CommunicationsBase Station 120 over the Network 115.

According to different embodiments of the present invention, a MobileCommunications Device 125 can be a cellular telephone, a personaldigital assistant, a pager, a text messaging device, a laptop, aportable music player, a two way radio, or any mobile device thatcommunicates voice or data. The Mobile Communications Device 125 and theMobile Communication Base Station 120 communicate via a communicationslink, at least a portion of which is wireless.

The Mobile Communications Device 125 may preferably be comprised ofhardware elements that are electrically coupled via bus, including amicroprocessor, a wireless receiver component, a wireless transmittercomponent, a computer-readable storage media reader, and a memory.Additionally, the storage media reader is further connected to a storagemedium. There may also additional components communicatively coupled tothe device, including an output component, such as a screen, display, orspeaker, and an input component such as a keyboard, touchscreen, ormicrophone. Those skilled in the art will recognize that this is but oneof a number of possible configurations for the Mobile CommunicationsDevice 125.

The Mobile Communications Device 125 is also coupled to a receivercomponent which enables the reception of location based information,also referred to herein as “data which identifies the location of thedevice,” “location data,” “location based data” or “locationinformation.” The receiver may be coupled to the Mobile CommunicationsDevice 125 in any suitable manner known in the art. By way of example,it may be an integrated component or may be a stand alone receiverotherwise communicating with the Mobile Communications Device 125.

The location based information may be in the form of Satellite 130location information, cellular location information, network analysis oflocation information, location information specific to a building, orother means for location determination. The location based informationmay be based on triangulation using cellular towers or access points.GPS related location information is discussed in greater detail below.Alternatively, cellular carriers may employ other means of locatingcellular telephones and other mobile computing devices using cellulartowers. By way of example, the time difference of arrival, angle ofarrival, and location pattern matching methods are well known in the artas alternative means of obtaining location information.

According to some embodiments, the location based information may be inthe form of a Global Positioning System (“GPS”) coordinates. Toillustrate how the Mobile Communications Device 125 receives andtransmits location information, GPS will be used. However, one skilledin the art will recognize that similar principles could be applied withother location based information. GPS is navigation system whereinlocation information is ascertained from a constellation of deployedsatellites 130. GPS provides continuous positioning and timinginformation anywhere in the world, utilizing very accurate atomicclocks. GPS is a one way system, wherein users only receive information.

The design of the GPS system attempts to ensure that four (4) or moresatellites 130 will always be visible. With the timing and positioninformation received from the satellites, the Mobile CommunicationDevice 125 or Server Computer System 105 “triangulates” the position ofthe Mobile Communications Device 125. GPS systems can also measurealtitude, speed, and direction of travel. Those skilled in the art willrecognize that as technology evolves and new generations of satellitesare launched with the GPS system, some of the characteristics of thesystem may change.

Each GPS satellite continuously transmits a microwave signal comprisedof two carrier frequencies, modulated by two digital codes and anavigation message. The two GPS carrier frequencies are generated at1,572.42 MHz (L1 carrier) and 1,227.60 MHz (L2 carrier). The two GPSmodulation codes are called coarse acquisition (“C/A Code”) andprecision (“P Code”). Each code is comprised of a stream of binarydigits, and is considered a pseudo random noise (“PRN”) code. However,the codes are generated using a complex mathematical algorithm. Theprecise code modulation for each satellite differs. The C/A code ismodulated onto the L1 carrier only, whereas the P Code is modulated ontoboth the L1 and L2 carriers. The navigation message is added to bothcarriers as binary biphase modulation.

According to various embodiments, the Mobile Communications Device 125receives a GPS signal and retransmits the signal directly to a ServerComputer System 105 via a Mobile Communication Base Station 120. Signalprocessing, wherein 1) the distances to the GPS Satellites are computedthrough the digital codes (pseudoranges), and 2) the satellitecoordinates are computed through the navigation message, may beundertaken by the Server Computer System 105. Alternatively, the MobileCommunications Device 125 may process the GPS signal itself. Accordingto other embodiments, the Mobile Communications Device 125 partiallyprocesses the signal with built in software. According to still otherembodiments, the Mobile Communications Device 125 processes the signal,and determines the GPS measurements and transmits the GPS measurementsin a data format. By way of example, the format may be RINEX, NGS-SP3,RTCM SC-104, or NMEA 0183. Those skilled in the art will recognize thatany number of proprietary formats may be used as well. According todifferent embodiments, a plurality of GPS antennas are used to determineposition location with greater accuracy.

The Mobile Communications Device 125 may, in some cases, transmitalternative location information to the Server Computer System 105.According to some embodiments, the signal strength from differentcellular towers may be used to determine position. In these cases, thesignal processing, wherein the signal strength and cellular toweridentification is used to determine position, is undertaken by theServer Computer System 105, not the Mobile Communications Device 125. Insome cases, the Device 125 may not provide the information; instead,cellular towers may triangulate the Device 125 and provide suchinformation to the System 105. Those skilled in the art will recognizethe different types of location information that may be received andretransmitted by the Mobile Communications Device 125. Therefore,according to the various embodiments that follow, the location basedinformation may comprise GPS coordinate data, GPS codes and a GPSnavigation message, or any location based information described in theapplication.

II. Mapping: One set of embodiments of the invention provides systemsand methods for mapping the location of a Mobile Communications Device125.

Other data may be included in thetransmission of GPS coordinate data, such as time, telephone, and userinformation. The Server Computer System 105 receives 220 the GPScoordinate data, and associates 225 that location information with aparticular user. The Server Computer System 105 maintains 230 a userprofile which includes information about the user and the Device 125 asdiscussed above. The user profile may include information about thecellular telephone necessary to identify the user, or a user may beidentified or otherwise authenticated in any other fashion known in theart.

The Server Computer System 105 correlates 235 the location data,information in the user profile relating to the user and the telephone,and mapping and location information in the electronic map database. Theuser profile may include information about the preferences of the userregarding the display of information. The Server Computer System 105creates 240 image data illustrating a map, and the location of theDevice 125. The image data is specifically formatted for display on theDevice 125 or class of devices, and is based on the information aboutthe device in the user profile. The Server Computer System 105 transmits245 the image data to the Base Station 120, which then forwards 250 theimage data to the Device 125. The image data may be transmitted in anemail, instant message, or other format. The Device 125 receives theimage data, and displays 255 the image data on a screen coupled to theDevice 125. The above exemplary embodiment merely represents an exampleof different embodiments of the invention.

According to different embodiments, the Mobile Communications Device 125is further configured to transmit additional data destined for theServer Computer System 105 which modifies the user profile from theDevice 125. The user may thus changes preferences regarding the contentof the image data from the Device 125, without logging on from apersonal computer. Alternatively, the user profile may be modified froma personal computer or other device connected to the Internet (e.g. viaa web interface, dedicated client, etc.).

The Server Computer System 105 may also be configured to store locationinformation received from a Mobile Communications Device 125 on astorage medium, and include a graphical representation of the historicallocations of the Device 125 within a time period. One skilled in the artwill recognize how historic location data can be correlated withinformation in the user profile and mapping and location information inthe electronic map database.

The user profile may also include preferences of the user identifyingthe circumstances in which the locations of a variety of businesses andother points of interest will be included in the image data. Thepreferences may include filters enabling different preferences accordingto times of day, geographic location, or other user input. The imagedata may then include a variety of graphical identifiers relating to thebusinesses and other points of interest, such as colors, dots, text, oricons. The identifiers may also comprise hyperlinks to additionalinformation about the businesses or points of interest.

According to some embodiments, the Mobile Communications Device 125 maytransmit the GPS coordinate data or other location information accordingto a variety of algorithms, one of which 400 b is discussed in detailbelow. According to other embodiments, the Server Computer System 105receives additional location data which identifies locations of otherDevices 125, such as the those of friends or family. Alternatively, theServer Computer System 105 may receive additional data identifying asecond location or locations, such as a destination or a possiblevacation spot. The user profile may be configured to include preferencesof the user specifying the circumstances in which the different usersand locations will be displayed. The preferences may include filtersenabling different preferences according to times of day, geographiclocation, or other user input. The image data may then include a varietyof graphical identifiers relating to the users or locations, such ascolors, dots, text, or icons. The image data may also include asuggested route through a selection of the users or locations.

Themethod can be used in a variety of systems, and other methods can beused as well, as is apparent to one skilled in the art in light of thisdisclosure.

According to some embodiments, the Mobile Communications Device 125 isagain configured to receive location based information. According tosome embodiments, the location based information is obtained throughcommunication with cellular telephone towers (although alternativeembodiments may use a variety of techniques to receive location basedinformation, as described above). The method is initiated when theDevice 125 receives 305 location based information. The Device 125transmits 310 the location data to the Mobile Communications BaseStation 120, which forwards 315 the data to the Server Computer System105. Other data may be included in the transmission of location data,such as time, Device 125, and user information. The Server ComputerSystem 105 receives 320 the location based data, and associates 325 thatlocation data with a particular user. As noted above, the ServerComputer System 105 may be fully located within a single facility ordistributed geographically, in which case a Network 115 may be used toprovide communication between or otherwise integrate differentcomponents of the Server Computer System 105. As described above, theServer Computer System 105 maintains 330 a user profile database, whichincludes information about the user and the Device 125. According tothese embodiments, the profile includes a listing of a plurality ofother locations to be visited by the user of the Device 125. The userprofile may include information about the cellular telephone necessaryto ascertain the user, or a user may be ascertained or otherwiseauthenticated in any other fashion known in the art.

The Server Computer System 105 correlates 335 the location data, theinformation in the user profile listing the plurality of locations to bevisited by the user, and mapping and location information in theelectronic map database. The user profile may also include informationabout the preferences of the user regarding the display of information.The Server Computer System 105 creates 340 data that describes asuggested route through the locations to be visited. The data may be ina variety of forms, including text, map images, dynamic directionarrows, or combinations thereof. The Server Computer System 105transmits 345 the suggested route data to the Base Station 120, whichthen forwards 350 the suggested route data to the Device 125. The datamay be transmitted in an email, SMS message, instant message, or otherformat. The Device 125 receives and displays 355 the suggested routedata on a screen coupled to the Device 125.

According to various embodiments, the user profile database alsoincludes a listing of a number of tasks to be performed by the user ofthe Device 125. The listing of tasks may include such things as“groceries,” “gas,” “cleaners,” “pick up kids at school,” “go to park”and so on. The user profile may also include a listing of a variety ofbusinesses and other points of interest and their associated locations.The user profile may further include a correlation between the locationsand tasks identified by the user. An application of the Server ComputerSystem 105 matches the tasks and the locations of businesses and otherpoints of interest in light of the location based information, toidentify locations to be visited by the user in order to accomplish thetasks.

By way of example, if “gas” and “groceries” are on the listing of tasks,the application would match a gas station and grocery store identifiedin the listing of businesses and other points of interest that are alsoin the vicinity of the Device 125. The design of such databases andmatching algorithms are well known by those skilled in the art in thedesign of relational database systems. According to certain embodiments,the listing of tasks is populated by data from a electronic personalcalendar embodied on a computer readable medium.

According to other embodiments, the user profile further includes anumber of preference levels corresponding to businesses and other pointsof interest. These preference levels may signify different ranges ofpreference or likeability that a user associates with a specificbusiness or point of interest. By way of example, at the user interface,the levels may be numbers, letters, colors, logos, icons or any otherfeature.

According to some embodiments, a destination or other location isreceived, and the data created by the Server Computer System 105includes the destination or other location. According to otherembodiments, the data created is image data which is comprised of a mapillustrating the location of the Device 125, other locations to bevisited by the user, and a suggested route.

According to differentembodiments, the locations to be visited by the user are illustratedwithout any suggested route.

IV. Efficiently Determining Location: Another set of embodiments of theinvention provides systems and methods for efficiently determining thelocation of a Mobile Communications Device 125. According to theseembodiments, the Server Computer System 105 receives location basedinformation transmitted according to a power efficiency algorithm 400 b,and filters and transmits location data according to the preferences ofthe user. FIG. 4A illustrates a method 400 a of efficiently determiningthe location of a Device according to a set of embodiments. The methodcan be used in a variety of systems, and other methods can be used aswell, as is apparent to one skilled in the art in light of thisdisclosure.

The method is initiated when the Mobile Communications Device 125obtains 405 location based information (e.g. receiving it from aSatellite 130). The Device 125 transmits 410 the location data to theMobile Communications Base Station 120, which forwards 415 the data tothe Server Computer System 105. Other data may be included in thetransmission of location data, such as time, Device 125, and userinformation. The transmission from the Device 125 may occur on intervalsbased on the algorithm 400 b described below, and illustrated in FIG.4B. According to different embodiments, the algorithm 400 b may bemodified by the user directly on the device, or by modifying the userprofile from the device or via a web interface. Alternatively, theServer Computer System 105 may otherwise transmit data which modifiesthe algorithm 400 b.

According to certain embodiments, the Device transmits the locationbased information on the earliest of the four following intervals:

-   1. Query from the Server Computer System 105: The first transmission    initiation factor 460 is a message received by the Device 125 from    the Server Computer System 105 requesting transmission 485 of    location based information. For example, if a second user queried    the Server Computer System 105 regarding location based information    about the user of the Device 125, the Server Computer System 105 may    be programmed to immediately query the Device for location based    information. The second user may want the information for tracking    or monitoring purposes.-   2. Distance Movement Metric: The second transmission initiation    factor 470 is a Distance Movement interval, wherein the Device 125    may be programmed to transmit 485 location based information    according to changes 465 in the location based information received    by the device. Merely by way of example, the Device 125 may be    programmed to transmit the location based information if the    information indicates a 500 meter change in location from previous    location based information transmission. Distance movement    transmission preferences may be longer or shorter, but shorter    distances may cause increased numbers of transmissions and drain    power. According to different embodiments, different distances can    be specified for each user or Device 125 during different times of    the day, different days, different locations, and so on. The    distance preferences for an individual user may be stored or    modified in the user profile database, and transmitted to the Device    125. Alternatively, a service provider could program the Device 125    for different distances. One skilled in the art will recognize the    variety of different programming options.-   3. Geographic Boundary Metric: The third transmission initiation    factor 475 is a Geographic Boundary metric, wherein the Device 125    may be programmed to transmit 485 location based information    according to movement 465 of the device across certain geographic    boundaries. The boundaries may correspond, for example, to certain    GPS coordinates. By way of example, the Device 125 may be programmed    to create a boundary around the grounds of a school, or the    buildings or classrooms within the school. The Device 125 transmits    the location based information if GPS coordinates indicate that the    geographic boundaries have been crossed. There may be any number of    geographic boundaries of varying sizes, but more boundaries and    smaller sizes may cause increased numbers of transmissions and drain    power. According to different embodiments, different boundaries may    be specified for each user or Device 125 during different times of    the day, different days, different locations, and so on. The    boundary preferences for an individual user may be stored or    modified in the user profile database, and transmitted to the Device    125. Alternatively, a service provider could program the Device 125    for different boundaries. One skilled in the art will recognize the    variety of different programming options.-   4. Time Interval Metric: The fourth transmission initiation factor    480 is a time interval, wherein the Device 125 may be programmed to    transmit 485 location based information within a specified time    period after each transmission. For example, the Device 125 may be    programmed to transmit the location based information every 30    minutes after a transmission of location based information, unless    location based information was transmitted from the Device during    the interim period according to one of the other 3 factors.    According to different embodiments, different time intervals can be    specified for each user or Device 125 for different times of the    day, different days, different locations, and so on. The time    preferences for an individual user may be stored or modified in the    user profile database, and transmitted to the Device 125.    Alternatively, a service provider could program the Device 125 for    different time intervals. One skilled in the art will recognize the    variety of different programming options.

According to other embodiments, two or three of the following four (4)metrics described above may be used: 1) Query from the Server ComputerSystem 460, 2) Distance Movement Metric 470, 3) Geographic BoundaryMetric 475, 4) Time Interval Metric 485. According to some embodiments,the Device 425 transmits the location based information on the earliestof the two or three selected intervals. According to other embodiments,the Device 425 transmits the location based information based onalternative factors related to the four (4) metrics.

Returning to FIG. 4A, the Server Computer System 105 receives 420 thelocation based information, and associates 425 that location informationwith a particular user. As noted above, the Server Computer System 105may comprise any number of computing devices 105 a, such as servercomputers, personal computers, workstations, or web servers. The ServerComputer System 105 maintains 430 a user profile which includesinformation about the user and the Device 125. The user profile may alsoinclude information regarding the circumstances in which the locationbased information should be stored in the Database 110.

According to some embodiments, the user profile includes preferences ofthe user of the Device 125 regarding the sharing of location basedinformation. The preferences may include information such as: a) whichother users or groups of other users may access location basedinformation, b) when each other user or group may access location basedinformation (times of day, days of the week), c) how granular theinformation requested may be (State, City, Street, etc.), or d) how eachother user or group may access location based information (for example,can they monitor or track the device). Additional preferences mayinclude whether an other user or group may access historical locationbased information, and which historical location based information canbe accessed. A user may also grant access rights on a per inquiry basis,such that rights would be required to be given by the user with eachinquiry about location based data. According to different embodiments,there are a number of different “access levels,” which correlate seriesof preferences. For example, one access level could be “Universal,”granted to a family member to enable access to all of the location data.One skilled in the art will recognize the variety of options availableregarding preferences and the user profile.

The Server Computer System 105 correlates 435 the location data, theaforementioned preferences of the user, and mapping and locationinformation in the electronic map database. The Server Computer System105 filters 440 the location data according to the preferences of theuser. The filtered data may be maintained in a variety of formats,including coordinate data, text, map images, or combinations thereof.The Server Computer System 105 transmits 445 the filtered data. Thedestination of the filtered data may be an other user trying to accessthe information from a mobile communications device or a personalcomputer connected to the Internet or Server Computer System 105. Thedata may be transmitted in an email, instant message, voice message, webpage, or any other appropriate format. The above exemplary embodimentmerely represents an example of different embodiments of the invention.

According to various embodiments, the Server Computer System 105 maystore the location data received according to preferences in the userprofile, or other parameters. According to some embodiments, other usersmay request location based information about the user of the Device 125.The other users may request “real-time” or historic information, orcertain subsets of information within these broader categories. Theother users may track, monitor, or otherwise receive location basedinformation about the user from a mobile communications device. Theother users may make tracking, monitoring, and other such inquiries fromthese other devices, without logging on from a personal computer.Alternatively, the inquiries may be made and information viewed from apersonal computer or other device connected to the Internet. The otherusers may receive information in a variety of forms, as noted above.According to some embodiments, the other users may indicate theirpreferences regarding the format of the information. In addition, theymay indicate the time period for tracking a user, or request certainperiodicity of updates or alerts based on time, movement, or boundarymetrics, as described above.

According to different embodiments, the Server Computer System 105 maytransmit the monitoring or tracking information (i.e. the filtered data)to the other users at intervals related to time, movement of the device,and crossing of geographic boundaries. These interval metrics 400 b arediscussed in detail above, and no further specific discussion isnecessary. According to these embodiments, the other user inquiringabout location information can receive updated (time interval)information and alerts (movement/boundary) about the location of theuser.

According to different embodiments of the invention, the userpreferences regarding the sharing of location based information may beprogrammed by a service provider, and administrator, or a user, or maybe preprogrammed onto the device. In some embodiments, the user may notchange the preferences. Alternatively, someone other than the user maybe the only person allowed to change the preferences, or the user may berequired to receive authorization before any changes are made.

According to different embodiments, the Server Computer System 105receives location based data from a number of mobile communicationsdevices. That location based information is then correlated withpreferences of the users associated with each device. These embodimentsenable the monitoring or tracking of multiple users.

V. User Defined Notification: Another set of embodiments of theinvention provides systems and methods allowing for user definednotification related to the location of a Mobile Communications Device125. According to some embodiments, illustrated in FIG. 5A, the ServerComputer System 105 creates 500 a information related to providers ofproducts and services for transmission under defined circumstances to aMobile Communications Device 125. According to other embodiments,illustrated in FIG. 5B, the Server Computer System 105 creates 500 binformation related to a user of a Device 125 for transmission underdefined circumstances to product and service providers. The methods canbe used in a variety of systems, and other methods can be used as well,as is apparent to one skilled in the art in light of this disclosure.

According to some embodiments, the Mobile Communications Device 125 is acellular telephone configured to receive location based information.However, the methods could be used with any other appropriate MobileCommunications Device 125. The method is initiated when the cellulartelephone receives 505 location based information. The cellulartelephone transmits 510 the location data to the Mobile CommunicationsBase Station 120, which forwards 515 the data to the Server ComputerSystem 105. Other data may be included in the transmission of locationdata, such as information related to time, telephone, and user. TheServer Computer System 105 receives 520 the location data, andassociates 525 that location information with a particular user. Asnoted above, the Server Computer System 105 may be fully located withina single facility or distributed geographically, in which case a Network115 may be used to integrate different components 105 a of the ServerComputer System 105.

The Server Computer System 105 maintains 530 the user profile. Accordingto these embodiments, the user profile includes a listing of the contactpreferences of the user of the Device 125. The contact preferences mayinclude information about the times, locations, types of product andservice providers of interest (specific providers or generalpreferences), format of contact, and other circumstances in which theuser prefers to be contacted. The user profile may include informationabout the preferences of the user regarding the preferred format and thedisplay of information. For example, a user may specify that between4:00 and 6:00 p.m., on certain roads, he or she would like to receive anemail with a map alerting him or her to certain types of restaurants.Product and service providers may include, without limitation, grocerystores, gas stations, health clubs, video stores, medical offices,museums, national parks, amusement parks, and any other retail orservice establishments. According to some embodiments, the user profilecontains preferences of the user regarding the sharing with suchproviders of location based information and other information in theuser profile.

The Server Computer System 105 also maintains 535 a database of productand service providers (“provider database”), contained in the Database110. The provider database includes information about certain productand service providers, and the information may include location,products or services offered, hours, special offers or coupons, reviews,and so on. Locations of the product and service providers are “logicallymapped” to the electronic map database, as described above. The providerdatabase also includes specific directives from each product and serviceprovider regarding the circumstances in which the Server Computer System105 should contact a user of a Device 125, along with directionregarding the information that should be included in the contact.According to different embodiments, the provider database also includesinformation about the circumstances in which the provider would like toreceive information about a user of a Device 125 in light of locationbased data and available information contained in the user profile.

The Server Computer System 105 correlates 540 the location basedinformation, the contact preferences of the user, the specific contactdirectives of the product and service providers, and mapping andlocation information in the electronic map database. The Server ComputerSystem 105 creates 545 data which includes information related to atleast one of the product and service providers. The data may be in avariety of forms, including text, audio messages, map images, dynamicdirection arrows, or combinations thereof. The Server Computer System105 transmits 550 the data to the Base Station 120, which then forwards555 the data to the user of the Device 125. The data may be transmittedas an email, a cellular telephone message, an instant message, or in anyother format. The above exemplary embodiment merely represents anexample of different embodiments of the invention.

According to different embodiments, the user profile further includes anumber of preference levels corresponding to business and serviceproviders. These preference levels may signify different ranges ofpreference or likeability that a user associates with a specificbusiness or service provider, or may correspond to classes of productand service providers. By way of example, a user may express highpreference for health food stores, and a low preference for fast foodrestaurants.

The Server Computer System 105 may store location based data,communication, responses, and other input from the user. According todifferent embodiments, the preferences levels are assigned based oninferences from the Server Computer System 105 from the collection andanalysis of data related to this stored information from the user.

According to some embodiments, the user may receive contact or alertsbased solely on changes in the location based data. For example, usersand product and service providers may have specific preferences for thetransmission or receipt of information based on vicinity parameters.According to different embodiments, a user may input information aboutan other location, such as a location that they will be visiting soon orare otherwise interested in. In so doing, the user (through their userprofile preferences) would be enabled to receive information or offersfrom product or service providers at that second location, or may shareinformation with product and service providers at that second location.

According to other embodiments, the data to be transmitted to the useris image data which may comprise a map illustrating the current or otherlocation of the user, and a representation of at least one of theproduct or service providers. The product and service providers may beshown as icons, which may also represent hyperlinks to furtherinformation about the provider. According to other embodiments, the datato be transmitted to the user is a suggested route to or through theproduct and service providers.

According to different embodiments, certain data contained in the userprofile is transmitted to a product or service provider. According tosome of these embodiments, many of the steps are similar (505–525, 555),but there may be a number of variances depending on the particularembodiment. According to the method 500 b illustrated in FIG. 5B, theuser profile 580 contains preferences of the user regarding the sharingof location based information and other information in the user profile(“sharing preferences”). Such sharing preferences may be very similar tocontact preferences, except that they relate to user profile informationto be shared, instead of preferences regarding contacts. Sharingpreferences may include information about the times, locations, types ofproduct and service providers of interest (specific providers or generalcategories of providers), amount of information to be shared, and othercircumstances in which the user prefers to share information. Forinstance, a user may specify that between 7:00 am and 8:00 am, nearwork, they would like to share information with specified coffee shops.

According to these embodiments, the Server Computer System 105 alsomaintains 585 a database of product and service providers, which may becontained in the Database 110. The provider database for theseembodiments is similar to the provider database 535 described above.This provider database 585 includes information about certain productand service providers, and the information may include location, hours,products and services offered, types of user profile informationrequested, times user information requested, and so on. Locations of theproduct and service providers may be “logically mapped” to theelectronic map database, as described above. The provider databaseincludes specific directives from each product and service providerregarding the circumstances in which the provider would like to receiveuser profile information from the Server Computer System 105, along withdirection regarding the information that should be included (i.e.“Reception Preferences”). Such information may include times of day,geographic location of user, user characteristics (income, age, gender,etc.).

The Server Computer System 105 correlates 590 the location basedinformation, the sharing preferences of the user, the receptionpreferences of the product and service providers, and mapping andlocation information in the electronic map database. The Server ComputerSystem 105 creates 595 data which includes information related to asubset of a user profile. The Server Computer System 105 may transmit550 the data, this time to a provider.

According to different embodiments, the user profile further includes anumber of access levels granting different “sets” of access rights tobusiness and service providers, or classes of business and serviceproviders. These access levels grant different depths of access to userprofile information. Access levels may reduce complexity and improveusability. Access levels may correspond to preferences of the userregarding the sharing of location based information and otherinformation in the user profile. Alternatively, users may grantsspecific access levels to specific product and service providers. Forinstance, a user may grant “minimum” access to location based data toall gas stations, while providing “moderate” access to a favorite chainof grocery stores.

VI. Keywords: A further set of embodiments provides systems and methodsfor providing information based on keywords, and location based datafrom a Mobile Communications Device 125. According to these embodiments,the Server Computer System 105 creates and transmits information relatedto keywords and the location of a Device 125 under definedcircumstances. FIG. 6 illustrates a method 600 of providing informationrelated to a keyword and the location of a cellular telephone accordingto a set of embodiments. The method can be used in a variety of systems,and other methods can be used as well, as is apparent to one skilled inthe art in light of this disclosure.

According to some embodiments, the Mobile Communications Device 125 is acellular telephone configured to receive GPS coordinates, although anyDevice 125 and any form of location based data could be used. The methodis initiated when the cellular telephone receives 605 location basedinformation, and data that contains a keyword. The receipt of thiskeyword data can be in a variety of forms. The keyword can be input astext through a keypad, touchpad, or other manual input device.Alternatively, an email, instant message, text message, web page, orother viewed or sent electronic text may be monitored or otherwisescanned for the existence of keywords. According to differentembodiments, audio input into a microphone can be interpreted to textwith speech recognition software. Such audio input may include wordsspoken by a user into the Device 125, received by the Device 125 from acall participant, or otherwise reproduced by a speaker coupled to thedevice, A variety of speech recognition software is commerciallyavailable, and well known in the art. The software may be stored in thestorage media or memory of the Device 125, or may be stored in theServer Computer System 105. The speech recognition software may thusinterpret the audio (or analog or digital recording of the audio) on theDevice 125 or at the Server Computer System 105.

Software related to the keyword filter may be stored in the storagemedia or memory of the Device 125, or may be stored in the ServerComputer System 105. Software with text filter functionality is wellknown in the art. A specialized microprocessor (such as a DSP chip)coupled to the Device 125 may be specifically configured to monitor forthe keywords, or the general microprocessor can provide thatfunctionality. The filter process can take place on the Server ComputerSystem as well, using suitable hardware.

The cellular telephone transmits 610 the location based data and keyworddata to the Mobile Communications Base Station 120, which forwards 615the data to the Server Computer System 105. Other data may be includedin the transmission as a part of the location and keyword data, such astime, telephone, and user information. The Server Computer System 105receives 620 the location based data and keyword data, and associates625 the location information with a particular user.

The Server Computer System 105 maintains 630 the user profile. The userprofile includes “keyword preferences” regarding the manner in whichkeyword information should be processed, if at all. According to someembodiments, the user may input specific keywords, and associate variousactions to be undertaken by the Server Computer System 105 if thekeywords are received (e.g. If “Hiking,” search for nearest hikingtrails that allow dogs). Alternatively, the user may input specificaction to be undertaken from keywords already listed in the user profileby the Server Computer System 105 (e.g. If “Coffee,” then search forindependent coffee shops). In other embodiments, the user profilecontains preprogrammed actions to be undertaken when keywords arereceived by the System 105 (If “Hungry,” search for local restaurants).Thus, according to different embodiments, both a) the keywords and b)the actions to be undertaken can be preprogrammed, modified, added, ordeleted.

A keyword database is maintained in the Database 110 by the ServerComputer System 105, wherein both the standard keywords and theassociated standard actions to be undertaken are stored. Standardkeywords and actions include those provided by the System 105 to be usedby all users. In addition, a listing of business and service providersand points of interest may be maintained, along with informationregarding their “logical location” mapping, as described above. Theirlocation, products or services offered, hours, special offers orcoupons, reviews, and so on may also be included. Each of the businessand service providers and points of interest is associated with at leastone keyword.

According to various embodiments, there are a number of further optionsfor the user profile database. The user profile may include keywordpreferences of the user regarding variable actions to be undertaken atdifferent times and geographic locations (e.g. If “Dancing,” and after10:00 p.m., search for local Discos). Also included may be preferencesrelated to general and specific interests, including product and serviceproviders of interest (specific providers or general categories ofproviders), points of interest, display of information, format, amountand nature of contact, and so on. The user profile may include a numberof preference levels corresponding to the providers and the points ofinterest. These preference levels may signify different ranges ofpreference or likeability that a user associates with a specificbusiness or point of interest. The user profile and keyword preferencesenable the customized presentation and content of information on apersonalized basis. The preferences can relate to keywords, associatedactions, or the listing of business and service providers and points ofinterest.

The Server Computer System 105 correlates 635 the location data, thekeyword, the preferences of the user, the keyword database, and mappingand location information in the electronic map database. The design ofsuch databases and matching algorithms are well known by those skilledin the art in the design of relational databases. The Server ComputerSystem 105 creates 640 information related both to the location of theuser and the keywords received, filtered by the keyword preferences ofthe user. The created data may be contained in a variety of formats,including text, images, map images, or combinations thereof. Image datamay include a variety of graphical identifiers relating to the points ofinterest and product and service providers, such as colors, dots, text,or icons. The identifiers may also comprise hyperlinks to additionalinformation. Image data may also be formatted to include a suggestedroute. According to different embodiments, the created data istransmitted 645 to the device.

According to different embodiments, the user may associate keywords withother users, thereby receiving location based information from otherusers. In other embodiments, keywords may be used in combination toformulate suggested meeting locations (i.e. “Brian”+“Hungry”=suggestmeeting at nearest Chinese restaurant). According to other embodiments,a user may input information about an other location, such as a locationthat the user will be visiting soon or are otherwise interested in. Inso doing, the user (through their user profile preferences) would beenabled to receive keyword related information from, for example,product or service providers at that second location.

It should be noted that the methods, systems and devices discussed aboveare intended merely to be exemplary in nature. Consequently, variousembodiments may omit, substitute, or add various procedures orcomponents as appropriate. For instance, it should be appreciated thatin alternative embodiments, the methods may be performed in an orderdifferent than that described, and that various steps may be added,omitted or combined.
